TREATMENT TABLE.

Application filed July 30,

To aZZ whom it may concern:

Be it known that I, JoHN V. lVloMnNIs, a

locked relative to each other independently of said, vertical adjustment and said adjustment to different degrees of inclination. Another object is to provide improved means to support and adjust a table top comprising a plurality of sections which are in turn adjustable and movable, as for instance oscillatable, relative to each other. Another object is to provide improvedmeans to sup port a table top as a whole and adjust it to diiferent positions of inclination where said plurality of top sections relatively movable and adjustable. Another" object is to provide improved means to re siliently and adjustably support one of the table top sections considerable portion of the weight of a patient and to thereby enable an operator to readily adjust the top section with the weight of the patient thereon. My invention also comprises certain details of form, combination, and arrangement, all of which will be fully set forth in the description of the accompanying drawings in which:

The main table top section 33 is pivotally supported with reference to the frame 2 L by rotatably connecting it at 35 tocars or projections 3 L projecting upwardly from the The top section 33 is adjustable upon the centers '35 to different positions of inclination with reference to the frame 24;, and is automatically locked to any adjusted positionby means of arod or bar 36 which 33 and is movable endwise through a recess 37 in a locking member" 38 pivotally connected at 39 to the frame 24:. The rod 36 may be drawn upwardly through the recess 37 to lift the top section 33 at its free end, and when released the bar 38 and rod 36 will automatically lock and hold the top section 33 to its elevated or adjusted position. In order to lower the free end of the top section "shanks 42 and collars it is necessary to depress the handle 40 of the locking member 38 whereupon the rod 36 is enabled to slide endwise downwardly through the perforation 37. Leg supports 4:1 are detachably mounted by means of their 43 with reference to socket brackets 44 attached to the corners at the free end of the top section 33, and thereby provide for a. patient being positioned sub *stantially as indicated in dotted lines Fig. 2

with reference to the table top sections, and from which position it is frequently desirable to adjust the top section 33 by elevating o-r lowering it at its free end after the patient is in position. Where the operator is of slight build, as for instance, a woman doctor, and the patient above the average weight, it would ordinarily be difficult for the operator to adjust the top section 33 with the patient in position, and in order to obviate this difiiculty I provide a forked arm or frame 45 projecting from approximately the pivot point35 to a posit'onat its free end below the frame 24. A carriage 46 is adjustable on the frame 24c and may be locked thereto by means of a set-screw L7. A'carriage 48 is adjustable upon the frame or arm 45 by means of a screw feed rod 49 turned by a crank 50. The carriages .46 and 48 are united by a spring 51, which tends to draw said carriages toward each other with more or less force, depending upon the positions of said carriages and the greater or less amount of leverage thereby attainable. The force exerted by the spring 51 upon the. arm 45 tends to assist an operator to lift and adjust the top section 33 with a patient in position thereon, particularly under the conditions above mentioned. When not re- 12, and

under side of the top section quired the carriages 4c and 4:8 or one of them may be adjusted to a position where the spring 51 will exert'practically no force, or if desired the spring may be disconnected from one of the carriages until again reuired for use.

The top section 52 is sup-ported with reference to the frame 2ft by means of a mem-. ber 53 pivoted upon the axle 54k journaled in ears upon the frame 24, and attached by a bolt 55 to the under side of the intermediate top section 52. At one end the top section rests upon cam members 56 plvoted upon the axle 57, and at the opposite end upon the cam members 58 pivoted uponthe axle 5 L. Hand levers 59 and 60 provide for rotating said axles and their cam members respectively, to thereby raise or lower either end of the top section 52 independently'of the opposite end, thereby providing four different positions of adjustment for the top section 52 relative to the frame 24, that is the position illustrated in Fig. 2, a position inclined to the right hand, that illustrated in and a position lower than Fig. 2, resulting from deto the left hand, a position inclined pressing both ends of said top section at the same time.

The auxiliary top with reference to the frame section 62 is supported 24 by means of a vertical axle 63 journaled in a sleeve 64 axle 70 upon which the top secin bracket 7 4c is threaded through the crossbar 7 5 of frame 67, and serves to adjust the section 62 to and from the section 52. Locking means not shown is employed to lock the section 62 rigidly relative to frame 67 against rotation on the axle 70 when desired. At the lower end of the shaft 63 is pivotally supported a frame 7 6 on which is mounted a carriage-77, adjustable along the frame 7 6 by means of a screw feed rod 78 rotatable by means of a crank 7 9, and carried by the frame.

end to the axle 66, and at its opposite end to the carriage 77, and tends to draw the free end of the frame 76 upwardly with greater or less force, depending upon the position of the carriage 77 with reference to the frame 76. This upward thrust of frame 76 is transmitted to frame 67 to support the top section 62 resiliently in a substantially hori zontal position, and at the same time leave top section 62 freeto be oscillated in a horizontal plane, by means of a tubular member 76. A spring 80 is connected at one,

-main table top-section rotatably 82 pivotally attached to the frame 76, an eyebolt. 83 67 and .Wlllll its threaded end telescoped in the tubular member 82, and a nut 84c-adjust ably threaded to the shank of said member 83 and resting upon the end ofthe member 82. Adjustment of the nut 84 elevates or lowers the free end of top sect-ion 62, and adjustment ofthe carriage 77 increases or de# creases the tension to support top section'62. A member 86 67 and adapted to be clamped by nut 87 to frame 7 6 serves tolock frames 67 and 76 together to hold the top section 62 nearly or practically in rigid position.

The mechanism herein illustrated and described is capable of considerable modification without departing from the principle of my invention.
